There were about 18 questions, which took about 40 minutes to answer, and left 20 minutes for me to ask questions. I was interviewed by one person (HR). I personally do not like being interviewed by HR because I find that they don't know/have experience working out in the field and can end up hiring the wrong people. A biologist might be better at hiring other biologists for this company. When I applied, they got back to me relatively fast. I interviewed the next week via Google Meet, got hired the next day, and started a week after the interview.
